Expansion Joints provide space between concrete slabs as a buffer for expansion on hot days and contraction when it is cold. Usually these expansion joints are installed during the initial installation of the concrete and are made of wood or some soft material so they can move with the expansion and contraction of the concrete. These joints vary in size from half-inch to an inch in width and three to four inches in depth. A slab without expansion joints will crack which will reduce the life of the concrete slab. These joints will crack all the way to the bottom of the concrete. If they come open, water will be allowed to run under the bed of the slab, eroding it and creating voids which can heave and cause major cracks and displacement in the concrete. Open joints can also be point of deterioration of the concrete because of weed growth and insect penetration.
As with most home repairs, you have two choices: DIY or hire a professional. But, keep in mind, if you make a mistake water could be leaking behind or under your concrete or pool deck, which could require replacing your entire deck or driveway if not caught. Granted, that is the worst case scenario, but worth keeping in mind. Call the professionals at the Texas Mastic Company and you can rest assured the repairs will be done correctly and in a timely manner so you can get back to enjoying your home.

There are two types of joints in concrete, Expansion Joints and Control Crack Joints. We repair and seal both types of joints.
Below are diagrams of each.
Control Crack Joints allow cracking in a controlled area as the slab settles with time. Usually these joints are cut into the slab after the concrete hardens. Control Crack Joints vary in size from one-eighth inch to one-quarter inch in width and a half inch in depth. A slab without these joints will crack in random patterns which ruins the look of the concrete and allows for damage from water intrusion thereby reducing the life of the slab.
Both type of joints will accumulate dirt and debris, allow grass or weeds to grow, and allow water to filter under the slab, etc. Water under the slab accelerates the settling of the concrete slab creating uneven concrete surfaces and cracks which is a very serious problem in Texas.
It is very important to keep joints in good repair. An annual inspection of joints should be on every homeowner's to do list. And knowing the proper way to repair these joints is very important. Many people just fill them up with a concrete material. This is not an optimal solution as the concrete will not expand and contract but will crack. A flexible joint sealer should be used to seal the joints to prevent water penetration, dirt and foreign matter accumulation while allowing the slab to move as it expands and contracts.

The expansion joints should be inspected yearly and replaced when you notice the sealant in the expansion joint is peeling, cracking or wood is rotting. Other indicators include pool tiles falling off, cracks in your concrete, or heaving (rising) in your concrete or pool deck. In fact, anytime you notice the concrete is changing it means you should inspect your expansion joints and mastic for seal leaks.
